Reading UTF8 strings from a server through http using MIDP

java, java-me, midp

Solution

Instead of reading bytes, read characters. Use an InputStreamReader API to convert bytes to characters and run through the UTF-8 encoder. It should be supported as part of the JavaME CLDC (JSR 30) profile; that's where the link points.

Try something like this:

c = (StreamConnection) Connector.open(
         myServer, Connector.READ_WRITE);
Reader r = new InputStreamReader(c.openInputStream(), "UTF-8");
StringBuffer sb = new StringBuffer();
int ch;
while((ch = r.read()) != -1)
    sb.append((char)ch + "->" + ch + "\n");

Problem

I want to read UTF-8 strings from a server that I have control of, using java MIDP. My server is sending UTF-8 data. The following code gets close: ``` c = (StreamConnection) Connector.open( myServer, Connector.READ_WRITE); InputStream is = c.openInputStream(); StringBuffer sb = new StringBuffer(); int ch; while((ch = is.read()) != -1) sb.append((char)ch + "->" + ch + "\n"); ``` I print the char and its code to debugging purposes. I think it is reading ASCII chars here, so, when I have some char that has its code above 127 then I get two chars, like the two examples bellow: letter á. UTF code E1 (hex). I get 195 and then 161 letter ô. UTF code F4 (hex). I get 195 and then 180 My question is, is there a way for me to read UTF characters directly. I've found some solutions in the web but none fits to the MIDP.
